My heart rate and steps have stopped syncing and don't show up in the connect mobile or web app. Activities still sync but also remain on the watch's current day tab, so in my daily activities I can see the activities for the past few weeks. This sounds reminiscent of what was reported here, but no solution was provided. I have tried rebooting and charging the watch several times. What can I do to fix this, do I have to reset the watch? Will that remove the activities on the watch that have not synced yet?
